Sahil Takiar commented on IMPALA-9748:
--------------------------------------
The same bug exists in Coordinator::HandleFailedExecRpcs as well and
ImpalaServer::CancelFromThreadPool. Basically, any place where the status
passed into TryQueryRetry is dropped.

> As discussed in
> [https://gerrit.cloudera.org/#/c/14824/24/be/src/runtime/query-driver.h@136],
> there is a bug in the error reporting path for query retries where it is
> possible for the error information set in TryQueryRetry is dropped. The
> impact is that the Status details (Status::AddDetail) set in TryQueryRetry
> won't get propagated to the client. This should only happen rarely, but it
> can only happen the ReportExecStatusRequestPB from a fragment contains a
> AuxErrorInfoPB entry, but no Status failure:
